its is alot easier to remove the exhuast and header pipe first, all you will need to replace is the header gasket, this takes alot less time and is also cheaper on parts. if your head is blown there will be signs of water in the exhuast outlets and your plug will look darker than normall. If there is moisture in there then its the head gasket and you have to remove the exhuast anyway.
Replacing the head gaskets is not hard you just read the manual and mark how things come out, i did mine for the first time it took about 3 hours to stripp down.
If you have no bubbles in the rads i doubt if the head gasket is blown, thats a sure sign the gasket is gone.
The other thing you can do is check is your valves its called a leak down test, you remove the exhuast header pipe and the carb/efi and pour a small amount of fuel into each of the vavle seats through the exhuast inlet and fuel inlets, make sure the valves are level so the fuel covers all around the vavles, this is a test to see if the valves are seating correctly as the fuel should not leak past the valves if it does the motor will not hold compression.
to do this you need to make sure the motors at TDC so all the valves are closed on the compression stroke.
if both of these thing are ok not sure where to go from here.

So your saying that the gasket could just be gone completely, instead of starting to blow with no bubbles in the radiator? What gets me is my oil when it's drained is totally fine, and it ONLY smokes on occasion and when I try and start cold. It looks like blue smoke sometimes too?
I mean how easily can a head gasket be blown? I've always kept lots of coolant in my radiators and made sure they weren't plugged up from anything. Plus I thought the gasser 4 strokes usually run cooler than others?
I have already gotten my valves check and adjusted from the shop earlier this year and they investigated my head and said it looked fine, but who knows how "well" they looked and what not. Especially since it started spooging out the white gunk the ride right after I got it back from them
Anyways I might take it in again to a different local shop and have them do some investigating since I don't have much time to look at it further. Any other thoughts let me know.
Thanks guys,
